Hi Paul,
I received my rotor housings and PP throttle assemblies last Friday.  The PP's are wonderful.  I hope that I can use them 'as is' by having them open from top to bottom rather than from bottom to top as we first designed.  I have to measure the port timing to see if the intake opening can be early enough (have to have the overlap) because of the ~ 1.9" thickness of the PP throttle valve.  I hope to do this Saturday.  I still can't believe that out of all the guys on the list that I am the only one planning to build a PP engine.

Paul, thanks for fabricating these for me.  
I look forward to seeing you at Tracy's this October.

Your welcome Ken. Sorry I did not have the guts to cut your rotor housings :-)

After thinking about it (after you mentioned that quite some time ago)
I am not sure top to bottom is the right way.
The six port has the high speed ports above the low speed ports
so that would imply bottom to top.
I think they are right as originally designed and as shown here.
Keep us informed on how this works out. I hope you can build some type
of dyno to get some HP curves on this idea.
